Is there a better way to making a 2d vector than this?

you could implement the Index trait fot get the elements:

Rayon transpose of Vec<Vec<T>>

You should avoid doing double level of indirection Vec<Vec<>> an alternative is define a type with a simple linear memory allocation and do the math for indexing elements, like so: use std::ops::{Index, IndexMut}; #[derive(Debug, Default)] pub struct Matrix<T> { size: (usize, usize), data: Vec<T>, } impl<T: Default + Copy> Matrix<T> { fn zeros(x: usize, y: usize) -> Self { Self { size: (x, y), data: vec![T::default(); x * y], } } pu…
